McuXpresso Preprocessor ignored

[SimoneColomboWEG]

Hi,

im using mcuxpresso version 24.12 [Build 148] [2025-01-10], i'm usually use a preprocessor for global define but with a wrong behaviur of code i've checked that a preprocessor define is ignored by compiler and not by intellisense.

i've attached a immagine that show PROTOCOL_ACTIVATED on preprocessor , correctly the code is masked from intellisense but compile (i've generated an error).

#ifndef PROTOCOL_ACTIVATED

static bool err;

uint16_t sumT = 0;

uint16_t sumR = 0

for( int i = 0; i < TRANSFER_SIZE; i++ )

{

sumT += masterTxData[i];

sumR += masterRxData[i];

}

if( sumT != sumR )

{

if( err == false )

{

PRINTF( "SPI Data err\r\n" );

err = true;

}

}

else

{

err = false;

}

#else

static uint16_t Error;

Error = CNT_Spi_Handler(pCNT_SPI_RX_Data); //&masterRxData[0]

// To Be Done Gestione Errori! //

#endif

where is the problem?!

Thanks for replied, i can't build in release, i don't use a different profile. i think is a problem that comes from a particular configuration from by project, is more of curiosity instead a real problem. i can work with a general define on code. if you want i can share with you my code (privatelly if is possible) if you can help me to find the issue.

Hi @SimoneColomboWEG,

Of course. You can share your code privately via a ticket on the following link: https://support.nxp.com/s/?language=en_US

Simply tag my name on the ticket's description and I will continue supporting you via that medium.

BR,
Edwin.

Hi @SimoneColomboWEG,

That's interesting. On my tests, when the conditional code is not true, the error messages of the controlled text do not matter (i.e. the compiler ignores the syntax errors, opposite to what happens on your side):

Does this happen in both Debug and Release build configurations for you?
